User blog comment:TheSinnohDuo/Setting up my pvp team! :D/@comment-34252725-20180403144647

You are really in need of a utility support I suggest ferothorn (this guy is pretty much a must on every team)he can land of leech seed and stealth rock in ease unless your facing a fire type or fighting type(on where I suggest to switch pokemon your gonna find him useful in the somewhat end of the battle since he can handle hits pretty easily for mega just put it on salamence and switch his movesets to

Double-edge/return

D claw

Roost (or something else I just prefer roost)

D dance

And also for marshadow I recommend this set

Drain punch/close combat

Shadow sneak

Spectral theif

Rock tomb/bulk up (prefer rock tomb since it can take out flying types unless your facing mandibuzz then switch)

Also once it comes out use shadownium Z or marshadownium z

With Groudon I would change the movesets to this

(Let it hold a chesto berry)

Precipice blades (main stab)

Any fire type mve that works well with it

Rest (I don't like it but it works)

Rock tomb (to lowen the opponents speed a bit)

And lastly when I was scrolling down the comments you said that your using sombody else's team well.... Do you even know how the team works if you do then ok your set but if you don't then what's the point of using that team I don't know if your familiar with competitive battling but all I gotta say is if your gonna play without not knowing the important stuff then don't do competitive battling
